A bipartisan group of House lawmakers have introduced legislation that would block the federal government from requiring technology companies to design devices with so-called “back doors” to allow law enforcement to access them. From a report: The bill represents the latest effort by lawmakers in Congress to wade into the battle between federal law enforcement officials and tech companies over encryption, which reached a boiling point in 2015 as the FBI tussled with Apple over a locked iPhone linked to the San Bernardino terror attack case.

Top FBI and Justice Department officials have repeatedly complained that they have been unable to access devices for ongoing criminal investigations because of encryption. FBI Director Christopher Wray has suggested that devices could be designed to allow investigators to access them, though he insists the bureau is not looking for a “back door.” The bipartisan bill introduced Thursday would prohibit federal agencies from requiring or requesting that firms “design or alter the security functions in its product or service to allow the surveillance of any user of such product or service, or to allow the physical search of such product” by the government.
